Accentors are small, somewhat drab birds belonging to the genus Prunella within the family Prunellidae, native to the Old World, mainly found in Europe and Asia's mountainous regions. The genus was defined in 1816 by French ornithologist Louis Vieillot, with the dunnock as the type species. They are generally non-migratory but can make seasonal elevational changes to escape the coldest winters. Physically similar to sparrows but unrelated, they range from 14 to 18 cm in size and have thin bills suitable for their insect and seed diet. Most accentors are social except for the solitary dunnock, which is known for its unique "shuffle-wing" behavior during courtship displays. Breeding involves elaborate songs and typically involves building neat cup nests, with both parents caring for the young except for dunnocks, which leave the male out of nest-building and incubation. The birds' habitat spans from high scrubland just below the snowline to lower altitudes in winter, with some species living in regions as high as 17,000 feet. The Prunella genus includes species such as the Alpine, Japanese, and Siberian accentors, each adapted to their unique environments and demonstrating a variety of behaviors and breeding strategies.
